To a/ZZ whom it may concern:

Beit known that 1, EDWIN FREDERICK COM- BER, a subject of the Queen ofGreat Britain, and a resident of Selkirk, in the Province of Manitobaand Dominion of Canada, haveinvented a new and Improved Pipe-Wrench, ofwhich the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved pipe-wrenchwhich is simple and durable in construction and arranged to insure a rmgripping of the article and to permit of conveniently engaging the jawswith different-sized pipes.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a side elevation of the improvement with parts broken out.Fig. 2 is a plan View of the same with parts broken out, and Fig. 3 is atransverse section of the same on the line 3 3 in Fig. l.

The improved pipe-wrench consists, essentially, of a fixed jaw A and amovable jaw B, pivotally connected at C to the fixed jaw` A,

as is plainly illustrated in the drawings, the

inner or opposite faces of said jaws A and B being V-shaped andserrated, as at A B, so as to engage the pipe or other article at fourpoints, and thereby insure arm gripping. The jaw A is provided with arearwardly-extending arm D, passing through the forked upper end of thejaw B, and on the rear end of said arm is held a pivot E for a cam-leverF, preferably 'formed with two arms, having their forward ends Fprovided with cam-surfaces for engaging the backs B2 of the fork membersof the jaw B, so that when the camlever F is swung in the direction ofthe arrow a then said cam-lever, by the cani-surfaces F, presses on thebacks B to carry the jaw B toward the fixed jawA and firmly grip thepipe or other article.

At the inner end of the cam-lever VF is arranged a pivot G for a handleH, adapted to firmly grip the object.

be taken hold of by the operator, said handle H having a transverse slotH', containing a pin I, adapted to engage one ofa plurality of recessesF2, formed in the pivot end of the cam-lever F. A spring J, held on thehandle H, presses the pin in engagement with the corresponding recessF2. By the arrangement described the handle H is locked to the lever Fby the piu I, so that in working the wrench the operator takes hold ofthe handle H and swings the same in the direction of the arrow ot' togive the desired swinging motion to the cam-lever F and cause the latterto swing the movable jaw B toward the fixed jaw A, as previouslyexplained, and thereby By pressing the pin I rearwardly out ofengagement with a recess F2 and then swinging the handle H on thecam-lever F the operator is enabled to set the handle H at any desiredangle relatively to the cam-lever F, and when the desired position isreached the handle and cam-lever are again locked together by thespring-pressed pin I engaging the corresponding recess F2.

As the wrench is composed of but few parts, itis evident that it can bevery cheaply manufactured and is not liable to get out of order.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent* l. A pipe-wrench, comprising a fixed jawhaving an integral arm extending rearwardly, a movable jaw pivoted onsaid xed jaw, a cam-lever fulcrumed on said arm and engaging saidmovable jaw, to swing the latter toward the fixed jaw and a handleconnected with the cam-lever, as set forth.

2. A pipe-wrench, comprising a fixed jaw having an integralarm extendingrearwardly, a movable jaw pivoted on said fixed jaw, a cam-leverfulcrumed on said arm and engaging said movable jaw, to swing the lattertoward the fixed jaw, and a handle fulcrumed on the cam-lever and havingan adjustable locking connection with said lever, to actuate the latter,as set forth.

3. A wrench, comprising a fixed jaw having at its inner end arigidly-attached arm, a movable jaw mounted to work in opposition to thefixed jaw, and a cam-lever with means for operating it, the cam-leverbeing pivoted IOO on the outer end of the arm of the Xed jew Intestimony whereof I have signed my and extending alongside. of said armto enname to this specificata-ion inthe presence of Io gage the movablejaw. l lwosubseibing Witnesses.
